valve structure which lcontrols rthe lcom-L pressed air and the outlet of the fluid.

. A still further important object of the invention resides in the provision of a pump of this nature which is exceedingly simple in its construction, automatic, eilieient and l5 reliable in its operation, strong and durable, comparatively .inexpensive to manufacture, not likely to easily become out of order and otherwise well adapted tothe purpose for which it is designed. I

With the above and numerous other objects in view as will appear as the ldescription proceeds, 'the invention residesin certain novel features ofconstruction, and in the combination and arrangement of parts A as will be hereinafter more fully describedv and claimed.

In the drawing: l Figure 1 is a sectional elevation showing the improvedpuinp structure with the tank in a raised position.

Figure 2 is a similar view, showing the tank in a lowered position. I 1 Figure 3 is an enlarged djetail elevation of the-valve and valve operating mechanism. Figure 4 is an edge elevation thereof, and Figure 5 is an enlarged section through the tank.

Referring to the drawing in detail, it will t e top of the well, and has rockable thereon l a lever 7 as at 8. A rod 9 is pivoted intermediate its ends, as at 10. 'toa link 11, which is pivoted to one endl of the lever 7 as at 12.

A weight 13 is vadjustably mounted on the other end of the lever 7. A pair of pipes 14 and 15 are `mountedin the ends of the meinber 9 and extend down into the well through bearings 16 on the cross piece 5; The pipe 14 is attached to the top of a tank 17, while the pipe 15 projects through the top4 of the tank and terminates adjacent the bottom thereof in a check valve 18.` An inwardlyv opening check valve 19 is mounted in the bottom o f the tank 1 7. A flexiblehose 2O is connected to the top of the pipe 14 and to a T-ooupling 21 having branches 22 and 23 .projecting Vtherefrom. An elbow coupling 24 is connected with the branch 22 -and has connected therewith a valve 25, which in turn is vconnected with the T-coupling 26, to

s which leads a pipe 27, from a suitable source of compressed air, A compressed air gauge 28 is connected with the T-coupling 26. A

bracket29 is mounted on the valve .25 and has rockable thereon a lever 30, for actuat the valve 25, which is of that type' whld normally is closed'. The lever 30 is operated 4to open this valve 25. A bracket 31 rises 'from the supporting structure 6 andhas across piece` 32 mounted adjacent the upper end thereof. A rocker .34 is pivotally mounted intermediate its ends as at 35, above the cross piece 33 and a link 36 is pivotallj7 engaged with one end as at 37, and with the lever 30, as at 38. An elbow coupling 39 is connected with the branch 23 and has attached thereto a valve 40 from which rises apipe, 41. A bracket 42 is mounted on the valve and roekably supports a lever 43, which is actuatable to open the valve 40, said valve 40 being normally closed. A link 44 4is pivotally engaged. as at 45, with the lever 43, and is also pivotally engaged as at 46, 'with the rocker 34, Obviously, when the rocker is in one position, the valve 40 is opened and the valve 25 is closed and when in the other position the valve 20 is closed and the valve 25 opened. -TheI cross piece 32 functions as a stop for the rocker 34 as willv be quite apparent. A lever 47 is Divoted as at 48- to the upper end of the 'bracket 31 and has fingers 49 projecting laterally therefrom for engaging the rocker 34, torock the same as the leveris swung from one position to the other, On the upper end of the lever is a weight 50. A lateral extension 51 is provided on the lever 7 andhas pivotallv engaged with its extremity as `at 52. a link 53, which has a pin n and slot connection 54. with an intermediate portion ofy the lever 47.

v As is shown to advantage in Figure 1,

when the tank 17 is inthe raised position,

the compressed air valve 25 is opene and the valve 40 is closed and therefore the compressed air' will flow through the flexible pipe ror hose 2Q down the pipe 14 to force fluid from the tank 17 up the pipe 15 and out through the outlet 56. As soon as the compressed air fills the tank, said tank will rise from the position shown in Figure 2 to the position shown in Figure l, because the air accumulating in the tank 17 will make the tank buoyant, and therefore the -rising of this tank will close the valve 25 and open the vaive 40, so that the air from the tank may escape up through the pipe 14, through the flexible hose 20, through the branch 23,

coupling; 39, valve 40 and pipe 41, and fluid will enter through the check valve 19 to fill the tank until it is sufficiently heavy to sink again to the position shown in Figure 2, upon which the compressed air will be turned on again and this operation will be continued without attention on the part of an operator;

It is thought that the construction, operament of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

1. In a pump vmechanism of the class described, a cross piece adapted to be inserted in a well below `the level of the fluid, a supporting structure adapted to be supported above the well, a tank, a pipe, a second pipe, bearings on the cross piece through which the pipes are slidable, the first pipe connected to the top of the tank, the second pipe extending through the top of the tank terminating adjacent the bottom thereof, a check valve at the bottom end of the second pipe, a second valve in the bottom of the tank opening inwardly thereof, a lever supported on the supporting structure being pivoted intermediateits ends, counter-balancing means on the lever, a member conneet-cd to the top end of the pipe, a link supporting the member fromv one end of the lever, a flexible pipe connected to the irst pipe, branches leading therefrom, valves in the branches, means for connecting one of the valves with a source of compressed air,
